Brady declined to comment when asked Saturday if it was fair for people to link Guerrero to the matter, as shown by CLNS Media's Mike Petraglia:

WALKOFF: Tom Brady did not appreciate being asked about an association between Julian Edelman and Alex Guerrero following his PED suspension https://t.co/WO4Dvvd5hJ

Edelman, who missed the entire 2017 season after tearing his ACL during the preseason, was suspended for four games for violating the league's substance abuse policy. Edelman appealed the suspension by arguing mistakes were made in the testing and other processes, but his ban was upheld.

Guerrero himself was quick to deny any involvement in the failed drug tests, per NBC Sports Boston's Tom E. Curran:

From Alex Guerrero..."I’ve known Julian since his rookie year and he is a phenomenal athlete who takes his training seriously—it’s disappointing to hear today’s news. Elite athletes sometimes work with multiple coaches and health professionals as part of their training. 1 of 2

Alex Guerrero, 2 of 2
"Here at our facility, we take a natural, holistic, appropriate and, above all, legal approach to training and recovery for all of our clients. And anyone who would suggest otherwise is irresponsible, and just plain wrong."

Brady has worked with Guerrero ever since he tore his ACL back in 2008. And while their TB12 method has helped the 40-year-old quarterback stay healthy through the years, Patriots coach Bill Belichick implemented new rules for Guerrero this past season.

The trainer was no longer allowed to be on the sidelines during games or on the team plane, and Brady was the only player he was allowed to treat at Gillette Stadium.

Guerrero is known for his unconventional methods, with Edelman going as far as to call him "Mr. Miyagi" in April.

Edelman, of course, has become one of Brady's favorite targets through the years. The 5'10", 200-pound wideout has hauled in 425 catches for 4,540 yards and 24 touchdowns in eight seasons of action.
